LEAK-STOPPER FOR HOSE.

Specification of Letters Patent.

Patented July 28, 1908.

Application filed October 18, 1907. Serial No. 398,073.

T 0 all whom it may concern:

Be it known that I, DIXON G. KITZMILLER, a citizen of the United States,residing at Harrisburg, in the county of Dauphin and State ofPennsylvania, have invented cer tain new and useful Improvements inLeak- Stoppers for Hose, of which the following is a specification.

My invention has for its object to avoid the expense and delays whichresult from the fracture of flexible hose and more especially of thehose of air-brakes upon cars. A break of this character when occurringin connectionwith a train will at once cause the arrest of the train, itsometimes requires from fifteen minutes to an hour to detach the hosesection and replace it, and the train where the accident occurs is notonly delayed but frequently other following trains are correspondinglydelayed, or when the break ocours in the railroad yard the arrest of atrain may interfere with sending out a number of other trains.

My invention consists in devices, a number of which may be carried witheach train, whereby in case of the fracture of a hose the leak may bestopped in a few minutes and the train used until an opportunity occursto substitute a new hose for that injured, and to this end the saiddevice consists of a yoke carrying a clamp plate and a screw togetherwith a loose plate adapted to be clamped against the hose by the screw,as fully set forth hereinafter and as illustrated in the accompanyingdrawing, in which:

Figure 1 is a side view in part section of my device; Fig. 2 an insideface view of the loose clamp plate; Fig. 3 a section on the line 33,Fig. 2; Fig. 4 a section on the line 44, Fig. 3; Fig. 5 a view showing aclamp plate of different form; and Fig. 6 a view illustrating the deviceapplied to the hose section of a brake device.

The device consists essentially of a yoke A,

- a curved plate B adapted to the contour of the hose and carried by theyoke A, a set screw 0 carried at the opposite end of the yoke, and asecond curved plate D also adapted to the contour of the hose but looseand having one or more sockets a: into which the end of the set screwmay enter when the parts are in position upon the hose X, which, asshown, is a hose of one section of an airbrake device. The plate B issecured to the yoke A by a pivot 2 so that the plate may swing and adaptitself to its position upon the hose X, and the plate D is a free platein order that it may be applied in any desired position to the hose soas to swing upon its support and so as to properly cover the break inthe hose, after which it is clamped against the hose and the latter isclamped between the two plates by properly turning the set screw C.Preferably there area series of sockets 00 extending longitudinally andtransversely at the outer side of the plate D, whereby the plate afterbeing adjusted in any desired position may be securely held byintroducing the end of the screw into one of the sockets, any possibleslipping in any direction being thereby prevented.

To effectually sea the opening in the hose the inside of the plate D isprovided with ribs 3, 4, so arranged as to form one or more panels andthe plate D is so applied, if possible, that the opening or break in thehose Wlll come within the outline of one of these panels, the ribs beingforced into the surface of the hose. These ribs may be arranged in anysuitable manner.

In some classes of devices 'where the hose is secured to a fixture ofany kind it is expanded sli htly at the detached end. This is especiafiythe case in connection with the section of an air-brake hose, as shownin Fig. 6 and I therefore in some cases provide the device with one ormore loose clamping plates D, and oneof said plates is slightly taperedor wider at one end than at the other, as shown in Fig. 5, so as toattach it to the conical portion of the hose in case the break shouldoccur at this point.

It will be evident that in the use of the described device afterapplying the plate B to the hose against the side opposite that wherethe break has occurred, the yoke extending over the hose, the otherplate D may be applied in any desired position so as to cover the breakand, being a loose plate, there is no difficulty in adjusting it ascircumstances may dictate so as to secure the best results, the clampingthen being effected by turning the screw 0.

In order to prevent the device from being tampered with or detached byunauthorized persons, the screw 0 is preferably provided with an angularhead 5 which may be fitted with a suitable detachable key I carried bythe conductor or brakeman or other authorized person.

Without limiting myself to the precise conyoke and two curved platesandpins for supstruction and arrangement of parts shown i porting themat opposite ends of the yoke so and described, I claim: as to oscillatefreely, one of said plates hav- 1.
